This is a very versitile module, which also allows a dimmer function for Halogen downlights or 12-24VDC Motor Control to suitable devices.

The RGBW Controller is a universal, Z-Wave compatible RGB / RGBW controller. The RGBW Controller uses a PWM output signal, which enables it to control LED, RGB, RGBW strips, halogen lights and fans.
Controlled devices may be powered by 12 or 24 VDC. All IN and OUT terminals may be user conﬁ gured for LED control or 100KΩ signal readouts.

This relay can also be used as a 12V 4 Channel On/Off Power Controller, which makes it ideal for 12VDC remote or Solar Power applications.
